Hi.
Usually ISPs use Integrated IS-IS for their IGP
(at least the ones I've dealt with). IS-IS can
deal better with large flat networks and has better
convergence characteristics (milliseconds vs. 6-46s).
That said, you could certainly use OSPF as your IGP.
On CCO there is a document called "ISP Design Fundamentals"
which could help here (too lazy to look it up now...)
Best regards,
Oliver
